Application filed January 18, 192?,Seria1 No. 161,921, and in Switzerland April 13, 1926.

The loom frames and slays hitherto known have been constructed either for overpick or for underpiclnfor loose reed or for fast reed, for single-shuttle or for multiple-shuttle working, for light or for heavy fabrics, for non-automatic or for automatic working, without it being possible, on one and the same loom, to carry out at will all the kinds of work mentioned. Consequently for each kind of work special main frames, a special breast beam and a special slay are required, which considerably increases the cost of 1nanufacture. i

Now the present invention relates to a looni' frame and slay which enables all theabovementioned kinds of Work to becarried out and may consequently be desig ited a. unitary loom frame and slay, and such renders possible a considerable simplitication cheapening of the maini'lacture.

' This result is obtained according; to the invention owing to the fact that each of the two main frames has cut surfaces for the arrangementof the loom frame as an ovcrpick or as an underpick loom frame, as a loose reed or as a fixed reed loom frame, as a single-shuttle or as a multiple-shuttle loomfraine, for

lightor heavy fabrics of anydesiredmate rial, as a frame for a non automatic oras an automatic loom for pick and pick or terry weaving, and also has supporting spar tures bored by means of templates for the reen of litted bearing hubs for the' crank sLa i shaft for the/batten. The invention is l tl'ier characterized by the fact thatthe frame cross-bars connected. with the main. planes of the inner-cut surfaci L ithebrc; cegtion of a loose reed and of an auton'iatic ts of three main parts. which are constructor the optional use of the slay as a loose or reed slay, an over or as an underpicker 1 ay, as a singlashuttlc or a multiplo-shuttle as an automatic or non-automatic pick and pick or Turkish towelling slay.

In the case of the main frame A (F igs; l

to 4:) 1 and 2 denote cut surfaces on its outer sides for the reception of picking shaft bearngs for the arrangement of theloom as an .overpick orunderpick l'oomp 3, likewise on the-outer side of the main ilramelA, denotes cut surfaces for the reception of buffer sup- Figs. and'll are an elevation and a plan slay, taken on the ports for the. fixed reed deviccs for the my rangement of the loom. as afixed reed loom'. 4:, on the same side of the main frame A, denotes cut surfaces for the reception of auxiliary supports for the stiffening of the crank shaft for the loom drive for the employment of the loom'for high speeds of revolution, heavy fabrics of rather large overall widths of loom. 1), on the same side of the 'main frame A, denotes cut surfaces for the reception of adevice for letting off or deliv ering the warp, for the arrangement of the loom as an automatic loom or as a non-automatic loom. 6, on the same side of the loom denotes cut surfaces for the reception of a box motion "for the arrangement of the loom as a multiple-box or check loom and as a pick. and pick loom 7 and 8 are two holes bored in the lower part of the main frame A for the reception of the rocking shaft for the lay when employing the loom for light and heavy fabrics. 9 and 10 are supporting apertures in the main frame A for the reception of a bearing bush 11 (Fig. 8) for the crank shaft 12 and a bearing bush 11 of the same construction for the lower shaft 13. The holes 7 to 10 are bored by means of a template, whereby an exceedingly accurate supporting of the shafts is obtained, the distance between the axes of the shafts being constant for all frames. Each bearing bush 11 has flanges 11 for securing the bush to the frame by means of screws. These screws are only intended to hold the bush firmly in an axial direction, while they are relieved of any stress in a shearing direction in consequence of the fitting of the bearing bush into the hole bored in the frame.

The same bearing bush 11 may be employed either in a Vertical or in a horizontal position, and all parts are exchangeable.

On the inner side of each loom frame A, cut surfaces 14 (Figure l) receive the stop surfaces 15 of the front and rear crossbars 16.

The breast beam 17 (Figures 5 to 9) belonging to the unitary loom, is constructed so as tobe used for fixed reed, as shown in Figure 8, or for loose reed, as shown inFigure 7, or for automatic weft replenishment as shown in Figure 9. In this connection, Figure 7 shows the fastening of the adjustable angle for the arresting of the throw of the reed for loose reed 7 whilst Figure 8 shows the fabric-carrying ledge 8 and the spreading roller 8 for the fast reed loom, and Figure 9, the cut surface 9 for the single-shuttle and multiple-shuttle automatic weft replenishment.

If in a weaving loom having a loose reed, the shuttle stops short in the shed, the slay nevertheless, advances in the front position, as it is known, but the reed is thrown backwards, the loom is stopped and no tearing of the threads takes place.

The slay 30 (Figures 10 to 14:), belonging to the unitary loom frame and slay, consists of three main parts B, C and D and, as shown in Figures 12, 13 and 14, is designed for optional use as a loose reed 'or a fast reed slay, as an overpick or an underpick slay, as a single shuttle or a multiple-shuttle slay, and as an automatic or a non-automatic pick and pick or Turkish toweling slay.

What I claim is: V

A unitary loom frame and slay, comprising two main frames, each formed with cut surfaces adapted to enable the arrangement of the loom frame as an overpick and as an underpick loom frame, both as a loose and as a fixed reed loom frame, both as a singleshuttle and as a multiple-shuttle loom frame, both for light and for heavy fabrics of any material, and both as an automatic and as a non-automatic loom for pick and pick goods and terry weaving, said main'shields each being also formed with bearing apertures bored by means of templates for the reception of bearing hubs for, the crank shaft, the lower loom shaft and the rocking shaft, the loom frame further comprising cross-bars connected with the main frames in the planes of the inner out surfaces, a breast beam constructed for the reception of aloose reedand of an automatic weft replenishment, and a slay consisting of three main parts adapted to enable the slay to be used both as a. loose reed slay and as a fixed reed slay, both as an overpick slay and as an underpiok slay, both as a single-shuttle slay and as a multiple-shuttle slay, and both as an automatic and as a nonautomatic pick and pick and Turkish toweling slay.

In testimony whereof I have affixed my signature.
